Prescription Opiate Abuse Managed by GPs with Authorized Staged Supply Dr Nigel Hawkins - UWS Introduction Prescription opiate abuse is something that all GP’s are familiar with and so all GPs need to know how to manage it This talk is not about IVDU or ORT, it is about treating and containing the abuse of drugs that we all prescribe What upsets patients We may not say these words but this is what it often boils down to › Go away › Junkie › No › We cannot help you › We don’t want you here Staged supply Is a simple but effective way for GPs to manage their own patients who have become addicted to opiates It is not the same as prescribing methadone or buprenorphine/naloxone which involve higher levels of supervision To minimize incidents with your addicted patients All GPs should know about Staged Supply and how to prescribe opiates with a state authority It would be good if at least one doctor in the practice / suburb knew how to prescribe ORT Outline Definition Incidence Recognition Assessment Management Case presentation Discussion Definitions Abuse is when a patient is not taking their medications as prescribed by a single doctor Dependence is when a patient cannot cope without their medication Addiction is when a patient experiences tolerance and withdrawal and is physically and psychologically dependent on their medication Incidence of dependence 18 16 14 Past 12 months Life time % of group 12 10 8 6 4 2 0 <20mg 21-90mg 91-99mg Oral Morphine Equivalents POINT Study Campbell et al Pain Medicine 2015 >200mg Incidence of tampering, doctor shopping and diverting 14 tampering 12 doctor shopping % of group 10 re-routing 8 6 4 2 0 <20mg 21-90mg 91-99mg >200mg oral morphine equivalents POINT Study Campbell et al Pain Medicine 2015 Incidence of perceived dependence and side effects, lifetime OD and sharing 80 70 60 SE / dependence % of group 50 OD lifetime 40 sharing 30 20 10 0 <20mg 21-90mg 91-99mg >200mg Oral Morphine Equivalents POINT Study Campbell et al Pain Medicine 2015 Incidence of other drug use 60 benzodiazepines 50 illicit drugs % of Group 40 risky drinking 30 20 10 0 <20mg 21-90mg 91-99mg >200mg Oral Morphine Equivalents POINT Study Campbell et al Pain Medicine 2015 Incidence of moderate to severe depression and anxiety 70 60 depression anxiety % of group 50 40 30 20 10 0 <20mg 21-90mg 91-99mg Oral Morphine Equivalents POINT Study Campbell et al Pain Medicine 2015 >200mg What is the cause of the patient’s pain? Does the patient have a genuine cause of pain or is the patient simply addicted? Recognising Opiate Abuse If the patient runs out of their medications more frequently than expected If the patient is seeing other doctors for their medication If the patient is using other addictive drugs If the patient’s pain persists for longer than two months If the patient looks drug affected or has track marks If alerted by doctor shoppers or real time services New patients Care should be taken with new patients Very pesistent patients Asking for a specific drug that is prone to abuse Look at the patients arms Consider doing a urine drug screen (UDS) Talk to doctor shoppers What is the quantity being consumed? How many times the recommended therapeutic dose (for pain) is the patient consuming History Records Doctor shoppers Real time services Is it for personal use? Is the patient selling** (diverting) their medication or is it for their own personal use? If there is any doubt about this then the patient will need to have at least a week of supervised daily doses **Patients who sell their medication should not be entertained What other drugs are being used? Alcohol Tobacco Cannabis Speed Valium Heroin Cocaine What is the patient’s social setup? Working? Homeless? Transportation? Social supports or liabilities? Criminal record What co-morbidities exist? Diabetes Ischemic heart disease Cirrhosis Renal impairment Cancer Back injury Arthritis Are there any mental health conditions? Depression Anxiety PTSD Schizophrenia Personality disorders Cognitive impairment What form of opiate is being used? Patches Tablets Syrups Films Opiate / naloxone preparations Over the counter preparations How is the patient using the drug? Is the patient disolving and injecting their medication? smoking their medication ingesting the medication If the patient is injecting their medication consider ORT How many doctors are involved? Is the patient visiting multiple doctors at different surgeries or do they stick to one doctor or one surgery? Who is the principal doctor? Who is going to manage the patient? Communication between doctors is essential Somebody needs to take responsibility for the patient This should be documented in the patient’s record Children at Risk Dependents must be taken into account Report any children at risk Examination Signs of opiate withdrawal Signs of opiate intoxication Track marks General appearance and hygeine Signs of liver disease Is the patient in pain Management of Prescription Opiate Abuse Single prescriber Authority to prescribe Staged supply Opiate Naloxone preparation Opiate replacement therapy** ** if very large quantities or intravenous drug use or if buying street drugs Are you the principal doctor? Is there another doctor who knows the patient better? Is there another doctor who is authorized to prescribe opiates? What is to stop you taking over the management of the patient? What is the point of getting an authority to prescribe? Getting an authority to prescribe after two months would guard against multiple prescribers if all doctors did this Getting an authority shows the authorities that you are taking precautions to prevent doctor shopping and it therefore confers some degree of immunity against prosecution or disciplinary action What is Staged Supply? Staged supply is when only part of the script is dispensed to the patient in a set interval and the remainder of the script is retained by the pharmacy This must be done with the knowledge of the prescriber and the permission of the patient It may be initiated by the pharmacist, the doctor who prescribes or by a carer / case worker How does staged supply help with Addiction? From the patient point of view: › It is better than nothing › It requires more effort to get the medication › It is harder to take more medicine than prescribed › It “puts the breaks on” › It prevents the patient running out of medication early Staged Supply From the doctors point of view: › It requires a little more communication with › › › › the pharmacist It ensures that the patient will not overdose on the medication prescribed It tends to screen out people who sell their medicine It saves dumping the patient It requires the doctor to convince the patient that this is the best option for them Staged supply (continued) Examples: 2 oxycontin tablets dispensed daily 4 targin tablets dispensed second daily One fentayl patch dispensed every 3 days One norspan patch dispensed weekly Seven suboxone films dispensed weekly Handwritten scripts Reviewing staged supply If patients are going well then the frequency of pickup can be reduced If patients are not doing well and running out of tablets too soon, then the frequency of pick up can be increased up to even daily If patients are going elsewhere to get opiates, then ORT will need to be considered Frequency of Pickups Doctor More frequent pickups Risk Desperation Patient What form of opiate? If there is a risk of injection or diversion then an opiate-naloxone preparation such as targin or suboxone should be used Otherwise staged supply with an authority could be used with any opiate Staged supply of opiates Staged Supply ORT Rational IVDU Reliable Very high quantities Prescription abuse Illicit / street use Opiate Replacement Therapy (ORT / OST) Opiate replacement therapy only differs from Staged Supply in the level of supervision and the medicines used are more tightly controlled Treatement usually begins with supervised daily doses of methadone or buprenorphine-naloxone The pharmacy must be acredited, the doctor authorized and the patient registered ‘Over the counter’ Opiates Staged supply will not work for ‘over the counter’ opiate abuse as the drugs are freely available and out of the doctors control When severe enough, addiction to ‘over the counter’ preparations can be managed with opiate replacement therapy Case Presentation To prescribe or not to prescribe? Is it reasonable to withhold the medication from the patient? Would obtaining an authority stop this patient doctor shopping? Would staged supply put the breaks on this patient’s opiate abuse? Would an opiate-naloxone preparation be useful? Question Time
